Perceived Hardness of Virtual Surface: A Function of Stiffness, Damping, and Contact Transient
Published in Proceedings of the 2021 IEEE World Haptics Conference, 2021In this paper, we are concerned with the combined case: the perceived hardness of a virtual surface rendered by the spring-damper model with a contact transient, in the tool-mediated perception.

Motion Effects: Perceptual Space and Synthesis for Specific Perceptual Properties
Published in IEEE Transactions on Haptics, vol. 15, no. 3, 2022This paper constructs a perceptual space that accounts for many motion effects based on their perceptual distances and then demonstrates smooth–rough and irregular–regular as its two primary perceptual dimensions.

Generating Real-Time, Selective, and Multimodal Haptic Effects from Sound for Gaming Experience Enhancement
Published in CHI '23: Proceedings of the 2023 CHI Conference on Human Factors in Computing Systems, 2023We propose an algorithm that generates a vibration, an impact, or a vibration+impact haptic effect by processing a sound signal in real time for gameplay.
